  "details": "## Summary\n\nFive Filament `groupedBulkActions` blocks across the Shopper admin Livewire pages omit the `-\u003eauthorize(...)` permission gate, while their per-record sibling actions (and other Shopper Index pages such as `Pages/Settings/Currencies.php`, `Pages/Reviews/Index.php`, `Pages/Collection/Index.php`, and `Pages/Discount/Index.php`) correctly chain `-\u003eauthorize(...)`. Each affected page\u0027s `mount()` only requires the read-only `browse_*` permission, so a low-privilege staff user holding only the read permission can drive the bulk endpoint via the standard Livewire `callTableBulkAction` flow and execute state-mutating operations they were never granted. The vulnerability is the same class as GHSA-f946-9qp6-vgch and GHSA-j328-xmgp-j4q3 (read-only permission gating a write action), just on a different surface (Filament 4 `groupedBulkActions` rather than top-level Livewire methods).\n\nA staff user holding only `browse_attributes` can permanently delete every product attribute in the catalog (cascading break of every dependent product variant). A user holding only `browse_tags` can permanently delete every product tag. Users holding `browse_brands`, `browse_categories`, or `browse_suppliers` can flip the visibility (`is_enabled`) of every brand/category/supplier in bulk, sabotaging storefront catalog visibility.\n\nCVSS 3.1: `AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H` = 8.1 High. CWE-285 (Improper Authorization) and CWE-862 (Missing Authorization). The attacker has low privilege (browse-only staff role), no user interaction, network reachable.\n\n## Vulnerable components (paths relative to repo root)\n\nAll references are HEAD = commit `ac9a760` on `master` (the very commit that closed the previous wave of authorization-drift bugs from GHSA-j328-xmgp-j4q3).\n\n### 1) `packages/admin/src/Livewire/Pages/Attribute/Browse.php`\n\nMount at line 36\u201339 requires only `browse_attributes`.\n\n- Lines 106\u2013122: `DeleteBulkAction::make()` has NO `-\u003eauthorize(...)` chain (the surrounding per-record `delete` action at lines 95\u2013104 correctly does `-\u003eauthorize(\u0027delete_attributes\u0027)`).\n- Lines 123\u2013138: `BulkAction::make(\u0027enabled\u0027)` has NO `-\u003eauthorize(...)`.\n- Lines 139\u2013155: `BulkAction::make(\u0027disabled\u0027)` has NO `-\u003eauthorize(...)`.\n\nNet effect: a `browse_attributes`-only user can **delete every row in the attributes table**, and toggle `is_enabled` on every attribute in one request. Deleting an attribute cascades into every product variant that references it via the `attribute_product` pivot.\n\n### 2) `packages/admin/src/Livewire/Pages/Tag/Index.php`\n\nMount at line 39 requires only `browse_tags`.\n\n- Lines 96\u2013108: `DeleteBulkAction::make()` has NO `-\u003eauthorize(...)` chain (the per-record `delete` action at lines 79\u201394 correctly does `-\u003eauthorize(\u0027delete_tags\u0027)`).\n\nNet effect: a `browse_tags`-only user can delete every `ProductTag` row.\n\n### 3) `packages/admin/src/Livewire/Pages/Brand/Index.php`\n\nMount at line 37\u201340 requires only `browse_brands`.\n\n- Lines 97\u2013112: `BulkAction::make(\u0027enabled\u0027)` has NO `-\u003eauthorize(...)`.\n- Lines 113\u2013129: `BulkAction::make(\u0027disabled\u0027)` has NO `-\u003eauthorize(...)`.\n\nNet effect: a `browse_brands`-only user can flip `is_enabled` on every brand. Disabling all brands removes them from the storefront catalog. The per-record edit/delete actions and the `DeleteBulkAction` at lines 130\u2013148 are correctly `-\u003eauthorize(...)` gated \u2014 only the visibility bulk actions were missed.\n\n### 4) `packages/admin/src/Livewire/Pages/Category/Index.php`\n\nMount at line 38\u201341 requires only `browse_categories`.\n\n- Lines 102\u2013117: `BulkAction::make(\u0027enabled\u0027)` has NO `-\u003eauthorize(...)`.\n- Lines 118\u2013133: `BulkAction::make(\u0027disabled\u0027)` has NO `-\u003eauthorize(...)`.\n\nNet effect: a `browse_categories`-only user can flip `is_enabled` on every category. Same shape as Brand.\n\n### 5) `packages/admin/src/Livewire/Pages/Supplier/Index.php`\n\nMount at line 38 requires only `browse_suppliers`.\n\n- Lines 93\u2013108: `BulkAction::make(\u0027enabled\u0027)` has NO `-\u003eauthorize(...)`.\n- Lines 109\u2013125: `BulkAction::make(\u0027disabled\u0027)` has NO `-\u003eauthorize(...)`.\n\nNet effect: a `browse_suppliers`-only user can flip `is_enabled` on every supplier.\n\n## Reference comparison: places that ARE correctly gated\n\nFor reference, here is what the same pattern looks like in files that DID get the fix:\n\n- `packages/admin/src/Livewire/Pages/Settings/Currencies.php` lines 90\u2013129: every `BulkAction` chains `-\u003eauthorize(\u0027access_setting\u0027)`.\n- `packages/admin/src/Livewire/Pages/Reviews/Index.php` lines 105\u2013119: `DeleteBulkAction` chains `-\u003eauthorize(\u0027delete_reviews\u0027)`.\n- `packages/admin/src/Livewire/Pages/Collection/Index.php` lines 109\u2013128: `DeleteBulkAction` chains `-\u003eauthorize(\u0027delete_collections\u0027)`.\n- `packages/admin/src/Livewire/Pages/Discount/Index.php` lines 126\u2013145: `DeleteBulkAction` chains `-\u003eauthorize(\u0027delete_discounts\u0027)`.\n\nThe convention is established and applied elsewhere \u2014 these five files just missed it.\n\n## Proof of Concept\n\nThe attached file `tests/Admin/Livewire/Pages/Brand/AuthBypassPocTest.php` (added in this report) contains seven Pest tests, each acting as a `browse_*`-only staff user and invoking the bulk endpoint. All seven pass on master @ `ac9a760`:\n\n```\n   PASS  Tests\\Admin\\Livewire\\Pages\\Brand\\AuthBypassPocTest\n  \u2713 it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all brands via unguarded BulkAction\n  \u2713 it SHOPPER-2 PoC: read-only viewer can mass-ENABLE all brands via unguarded BulkAction\n  \u2713 it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all categories via unguarded BulkAction\n  \u2713 it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all suppliers via unguarded BulkAction\n  \u2713 it SHOPPER-2 PoC: read-only viewer can DELETE all attributes via unguarded DeleteBulkAction\n  \u2713 it SHOPPER-2 PoC: read-only viewer can mass-DISABLE all attributes via unguarded BulkAction\n  \u2713 it SHOPPER-2 PoC: browse_tags viewer can DELETE all product tags via unguarded DeleteBulkAction\n\n  Tests:    7 passed (32 assertions)\n```\n\nEach test seeds three records, signs in a user holding only the corresponding `browse_*` permission, calls `Livewire::test(\u003cPage\u003e::class)-\u003ecallTableBulkAction(...)`, and asserts the side effect (records flipped or deleted). For example, the attribute mass-delete test:\n\n```php\n$this-\u003eviewer = User::factory()-\u003ecreate();\n$this-\u003eviewer-\u003egivePermissionTo(\u0027browse_attributes\u0027);\n$this-\u003eactingAs($this-\u003eviewer);\n\nAttribute::factory()-\u003ecount(3)-\u003ecreate();\nexpect($this-\u003eviewer-\u003ecan(\u0027delete_attributes\u0027))-\u003etoBeFalse();\n\nLivewire::test(AttributeBrowse::class)\n    -\u003ecallTableBulkAction(\\Filament\\Actions\\DeleteBulkAction::class, Attribute::pluck(\u0027id\u0027)-\u003etoArray())\n    -\u003eassertHasNoErrors();\n\nexpect(Attribute::count())-\u003etoBe(0);\n```\n\nThe call uses the same `callTableBulkAction` helper Shopper\u0027s own test suite uses everywhere, which in turn drives the same Livewire `update` payload the browser would emit \u2014 so this is a faithful HTTP-level reproduction.\n\n## Suggested fix\n\nAdd `-\u003eauthorize(\u003ccorrect_permission\u003e)` to each of the five vulnerable groups, mirroring the pattern already used elsewhere:\n\n```diff\n // Pages/Attribute/Browse.php\n -\u003egroupedBulkActions([\n     DeleteBulkAction::make()\n+        -\u003eauthorize(\u0027delete_attributes\u0027)\n         -\u003elabel(__(\u0027shopper::forms.actions.delete\u0027))\n         -\u003erequiresConfirmation()\n         -\u003eaction(function (Collection $records): void { /* ... */ }),\n     BulkAction::make(\u0027enabled\u0027)\n+        -\u003eauthorize(\u0027edit_attributes\u0027)\n         -\u003elabel(__(\u0027shopper::forms.actions.enable\u0027))\n         -\u003eaction(function (Collection $records): void { /* ... */ }),\n     BulkAction::make(\u0027disabled\u0027)\n+        -\u003eauthorize(\u0027edit_attributes\u0027)\n         -\u003elabel(__(\u0027shopper::forms.actions.disable\u0027))\n         -\u003eaction(function (Collection $records): void { /* ... */ }),\n ])\n```\n\nApply the equivalent change to `Pages/Tag/Index.php` (`delete_tags`), `Pages/Brand/Index.php` (`edit_brands` for enable/disable), `Pages/Category/Index.php` (`edit_categories`), and `Pages/Supplier/Index.php` (`edit_suppliers`).\n\nA regression test for each file (acting as a `browse_*`-only user and expecting `assertHasErrors`/`AuthorizationException`) would lock in the fix, matching the regression tests added for #514.\n\n## Resources\n\n- Prior advisories of the same class (read-only permission gating a write action): GHSA-f946-9qp6-vgch, GHSA-j328-xmgp-j4q3 / GHSA-vw82-3966-f9mr.\n- Same-shape fix: commit `ac9a760` (PR #514). Five Filament bulk-action groups did not receive the corresponding `-\u003eauthorize(...)` chain.\n- CWE-285 Improper Authorization, CWE-862 Missing Authorization.\n\n### Credits\n\nReported by Vishal Shukla(@shukla304) using sechub.dev AI Agent\n\n### Support\n\nIf this disclosure was useful and userswould like to support continued open-source security research and responsible-disclosure work, they can sponsor at https://github.com/sponsors/therawdev \u2014 Shopper is thankful for those keeping open source safe.",
